he machine is match: with a air of side cheeks or frames 1 each having thereon four upward extensions or brackets within each of which there provided a bearing for one encl of a screwed spinglle 5 The spindles ve blocks 5 aii iustably screwed thereon and between these blocks the copper rolls 3 are moiintecl as usual. Secured upon each of the extensions i is a bracket 6 having therein a vertical slot or opening 7 from top to bottom of Whichthere extends a screw 8, and on the upper end of the screw there is secured a bevel Wheel 9. Secured on the i clinal sect horizontal spindles 11 upon which are bevel Wheels 12 in mesh with the bevel Wheels 9, and each spindle 11 has, on one end thereof, a hand wheel 13 by means of which the spiniiles 11 may be rotated in such manner as to rotate the vertical screws 8 at the opposite ends of any of the copper rolls 3 simultaneously andylocated above each copper roll 3 and parallel thereto, is a cross beam l iuhaving recesses therein for the reception of small wooden wedges 15 which bear on the roll 3 and hold same rigiiily in position and, formed on each end. of the beain'14 is a nut or screwed sleeve 16 through which passes one at" saici vertical screws 8 in such manner that she cross beam 1% may be raised or lowered by means of the bevel ear hereinioefore described. The beams 14 may time be readily acljiisted to suit copper rclis of 'varying diameters.

Liicaterl'bet'iveen the side checks or frames 1, 52, is a vertically adjustable bed 17 which su iportedby our vertical screws 21. whose screw threads engage the threads of screw sockets 21 on the frames 1, 2. The screws are provided with worm wheels 18 adapted to be. operated by means of a hand )VliEll 19 and shaft HP through worm and bevel gear 20 suitably mounted in bearing brackets (le pending from the bed or base 17 in suchmanner that on the hanil wheel 19 being ro- Rated the bed if can be raised or lowereil by turning; the screws 2i.

hantl Wheel. 13 and of'sliding transversely of the machine is a table 22 which is provided, on its underside, with depending guides 23 adapted to slide on the surfaces 23 (see Fi 2) ofthe bed 17 and projecting upward rom the table'22 are two sets of bearings 24 each pair carrying a shaft 24 with wheels 25 thereon upon which the frame 26 rests and'is capable of a sliding, movement longitudinally of the machine. The table 22 is traversed transversely of the machine by means of a nut 27 which depends therefrom and works u on a horizontally arranged screwed spind e 28 mounted in end hearings in the bed 17 and having on one end thereof an index wheel 29 made with peripheral teeth and having an index pointer 30 secured pivotally adjacent thereto. The. frame 26 is traversed, upon the wheels 25, longitudinally of the machine, in the manner hereinafter described.

Slidably fitted in the frame 26 and be tween cross ieces 26 therein (see Figs. 5 and 6) are our boxes 31 which may each be. moved vertically so as to bring a printing plate 32 therein into or out of engagement with a copper roll, there being rovided inthe frame 26 a longitudinal shait 57 having a series of cams 58, one beneath a late 31 slidably fitted in each box 31. I The oxes 31 are preferably square. Bearing against the upper side of the plate 31 of each box is a cam 32* on a spindle 33 ro-tatably carried in the box and capable of being turned'by a key passed through a hole 26 in the frame 26. ()n the end of the shaft 57 is a lever 59 from whose end a weight is hung so as to normally rotate the shaft 57 into such a position that the cams 58 push up the boxes and retain all the printing plates 32 in close engagement with the copper rolls. Should slight adjustmentbe required for any particular plate 32 it can be effected by manipulating its cam 32.

' The'spindles 5 at one side of the machine are each provided with a worm wheel 33 and located beneath the worm wheels 33 is a worm shaft 34 carried in bearing brackets 35 on the side frame 1 and engaging each wheel 33 is a worm 36 on the shaft 34, which is provided with a hand wheel 37 by means of which the rolls may be all rotated simul' taneously by hand for the purpose of adjustment and, in adjusting the rolls in a rotary direction accuracy of position tor printing or marking on is insured'by means of an index wheel 38 secured on the end of oneof the roll spindles 5, a swiveling pointer 39 being pivotally carried on the frame 1 adj acent thereto. For rotating the rolls,

when desired, by power, the shaft 34 has at its end, a bevel wheel 41 which gears with a bevel wheel 41 carried in a bracket 41 (Fig. 4). On a short sleeve 43 is keyed a belt pulley 40 and a bevel wheel 43* having a collar with which the forked end of a lever 42 fulcrumed on the bracket 41" engages. By

manipulating the rod 42 the bevel wheel 43" can be ut into and out of engagement with the wiieel 41 and in this manner the power drive can be put into and out of en gagement with the wheel 41 and in this'mam ngr the power drive can be put on or taken 0 r a For traversing the frame 26 beneath the rolls at a speed exactl equal to the surface speed of the copper toils variable speed gear is provided for moving the frame so that the machine can be used for rolls of difl'erent diameters. To this end there is slidably keyed on the shaft 34 a. bevelwheel .43 which can be caused to gear with and drive a bevel wheel 41 by means of the rod andgiever 65'. The wheel 41 is on the upper end of a feathered shaft 45 mounted in bearin brackets 46 on the frame 1 and on this she 45 is a worm 47 which engages and drives a worm wheel 48 whose shaft 49 is mounted in bearings in extensions 50 of the bed 17 (see also Fig. 9). The worm 47 is held in position on the shaft 45 by brackets 51 on one extension 50.

Carried in the extensions 50 is a slide 53 which is made on its u per side with a dovetail 54 u on which slid ds a block 55 havin a screw w ereby it may he clamped to t e slide 53. I The slide 53 has a depending bracket 52 with a nut through which the screwed shaft 49 extends. Pivoteddn the block 55 is a channeled block 56 within the groove or channel of which works a. bar 61 pivotally connected to the underside of a winged extension 62 on the frame 26, the bar cators whereby the'angle made by the bar 61 with the line of movement of the frame 26 maybe ascertained. The pins would be provided with clamping nuts 63'. The 'bar 61 is'adjusted to the desired angle, to give the required travel of the frame '26 with the boxes 31 therein and is then clamped by the nuts 63. When the screw 47 is rotated the slide 53, block 55 and channeled block 56 are moved transversely with the result that the bar 61 and frame movelo-ngitudinally. By altering the angle which the bar 61 makes with the line of travel vof the frame- 26, the travel of the said frame may be varied as will be readily understood, and when the bar 61 is placed at exactly 90 to the said line of travel no motion is imparted to the frame 26. When it is desired to traverse the table 22 transversely of the machine by means of the traversingscrew 28 the sliding block 55 is unclamped from the slide 53 so as to be free to slide longitudinally thereof and on the completion of the transvrse adjustment" or movement the slide 53 and slidy s to mills 1 v- 5 w n C .6 av a. a. 11 \1 n. l, I
